A High Court injunction obtained by East Hampshire District Council's planning service prevented further construction on rural land at Jennie Green Lane in Medstead.
Development occurred over the Easter bank holiday weekend and an emergency stop notice was issued by the council on April 24 to prevent any further work.
After it appeared more had been done, the council sought the injunction. A planning application has now been submitted.
Cllr Tony Costigan, East Hampshire’s portfolio holder for property and ward councillor for the area, said: “Residents were very concerned to see apparently unauthorised and unlawful development taking place on a beautiful corner of the local countryside.
“Naturally we responded as quickly as we could and were prepared to go straight to the High Court to prevent further damage being done.
“East Hampshire District Council will always seek to take proportionate and reasonable legal action of this kind whenever we are faced with this type of totally inappropriate development of our natural landscape.”
The injunction was taken out against Peter Wenman, David Scard, Billy Wenman, Crystal Allgood and persons unknown for living or building on land west of Redwood Farm on the south-west side of Jennie Green Lane.
It prevents the four named defendants changing the use of the land, undertaking any engineering work, putting up any building or structure, bringing any more caravans or mobile homes on to the land, importing or depositing any material, excavating the land, living on the land or letting any other person live on the land.
Nobody not living there at the time of the injunction can live there now, nor can any caravan or mobile home not there at the time of the injunction be moved there.
The High Court will consider whether the injunction should remain in force on May 8, when the developer will have the opportunity to challenge the council.
